《GB/T 40308-2021气象仪器型号与命名方法》由TC507（全国气象仪器与观测方法标准化技术委员会）归口，主管部门为中国气象局。
Introduction
Analysis of the core content of the standard
| Classification hierarchy | Code rule | Example | Corresponding table number |
|---|---|---|---|
| Category code | First letter of Chinese pinyin | Ground observation instruments→D | Table A.1 |
| Group code | First letter of element characteristics | Wind measuring instrument→F | Table A.2-37 |
| Column code | First letter of principle/structure | Ultrasonic anemometer→S | Appendix of each category |
Key technical points
The model structure follows the DYZ1-2 format:
- D (ground observation instrument)
- Y (air pressure measurement group)
- Z (vibration simple series)
- 1 (first model number)
- -2 (second modified model)
Typical application: DWS3 represents the third type ground temperature sensor
Standard evolution background
This standard replaces the original scattered industry naming rules and achieves three major breakthroughs:
- Establish a unified coding system covering 236 types of meteorological instruments
- Introduce supplementary codes for intelligent equipment (such as Z2 for Internet of Things function)
- Add new equipment categories such as meteorological drones
Implementation suggestions
1. During the development phase of new instruments, the classification path should be determined by referring to Appendix A
2. Comprehensive measuring instruments are classified according to their dominant functions (such as DZD series)
3. The modification number needs to be incremented after the technical change review
